Hey, no problem.

I looked it up. It is a french expression meaning "of the highest quality", literally referring to behind the bundles of wood. It's vert old french so it might be used in Quebec and rural France.

This is brutal butchering of remembered French. I think it might be a bad translation but I'm reading it as The Back Woods lol. Derriere is behind or back. It could also be about someone's ass. Who knows?

I've drank them occasionally my whole life. Recently, it has become a nightly habit. I'm sad because I've run out. I only have caffeinated teas left, and it's far too late for that.
